EVERYDAY SCIENCE

Detailed explanation-1: -It means chemical energy converts into chemical energy but vice-versa is not possible. Hence primary cell can not be recharged once it is used.

Detailed explanation-2: -Cells that cannot be recharged are called primary cells. • In primary cells, the products slowly migrate away from the electrodes and are consumed by side reactions occurring in the cells.

Detailed explanation-3: -A primary cell or battery is one that cannot easily be recharged after one use, and are discarded following discharge. Most primary cells utilize electrolytes that are contained within absorbent material or a separator (i.e. no free or liquid electrolyte), and are thus termed dry cells.

Detailed explanation-4: -There are Two Main Types of Primary Cells/Batteries. Chemical composition of Zinc with Manganese dioxide forms these batteries. The electrolyte that is used in these types of batteries is potassium hydroxide, and since all the contents are purely alkaline, it is termed as an alkaline battery.

Detailed explanation-5: -The major difference between a primary cell and the secondary cell is that primary cells are the ones that cannot be charged but secondary cells are the ones that are rechargeable.
